extended one-level interbody fusion: For patients who have vacuum signs in the intervertebral disc adjacent to the surgical segment but are asymptomatic and not unstable, the intervertebral fusion surgery is extended to one segment and followed up immediately after surgery, 3 months, 6 months, and annually within 1 to 5 years. Take lumbar spine MR to determine the degree of degeneration progression of adjacent segments and whether revision surgery is needed. Take X-rays of the lumbar spine in frontal and lateral + flexion and extension positions, and CT-three-dimensional reconstruction to judge the bony fusion of the intervertebral fusion.
Study summary
The main objective of this study was to validate the clinical effectiveness of interbody fusion with a one-segment extension for the treatment of adjacent segmental space discs in the surgical treatment of lumbar degeneration.

Inclusion Criteria:
* The age was between 18-60 years old; patients with lumbar degeneration required 1-2 segment interbody fusion, and there were vacuum signs but no symptoms and no instability of the discs in the adjacent segments (power position slip ≤3mm and segmental angle change ≤10°); they agreed with the surgical plan and were willing to undergo long-term clinical follow-up, and signed an informed consent form.
Exclusion Criteria:
* Drug or alcohol abusers; those with abnormal liver or kidney function unsuitable for surgery; those with cardiac insufficiency unsuitable for surgery; those with severe metabolic and endocrine diseases unsuitable for surgery; those with severe lung disorders such as asthma and abnormal lung function unsuitable for surgery; pregnant and breastfeeding women as well as those who are planning to become pregnant in the near future; those who have participated in other clinical trials within 3 months; and those who are not suitable for participation in the experiment in the opinion of the investigator.
Primary outcome measure(s)
Surgical revision rate — Postoperative month 3 (±15 days), month 6 (±15 days), yearly for 5 years (±30 days) MR of the lumbar spine was taken at follow-up to determine the degree of progression of degeneration in the neighboring segments and the need for revision surgery.
